Kuqa Depression Grams - According To The Construct With A Typical Oil And Gas Reservoir Study Of The Accumulation Mechanism

The Keyi structure belt is took the most important domain as gas exploration in the Kuqa depression, It is vital significance of researching its the accumulating pattern and process of typical oil gas reservior for this local oil gas exploration. On the basis of the distribution of gas and source rock and geochemistry research, This article is analyzed the oil gas origin and accumination characteristic in yina2, dawanqi, tuziluoke oil gas pool, the knot shoulds the area structure evolution system to study the order of the period accumulation in Keyi structure belt oil gas and the pattern, the analysis gram controls the factor according to the structure belt oil gas the period accumulation, has pointed out the advantageous exploration direction. The research indicated that, This area oil destiny gathers has three issues, the first issue mainly is the Mt. yanshan - happy mountain early time three packs is the origin oil gas accumulation, although has been destructed, but the oil gas can be preservated in some ancient structures; The second issue is Kang Cun period, by three packs is and the Jurassic series production gas primarily, has the few Jurassic series coal formation hydrocarbon source rock few condensate entering which carries by a gas phase row of hydrocarbon, by now delayed the anticline already setting; The third issue is the Kuqa time, mainly is originally delays in the anticline the natural gas again shift to concentrate, possibly also has a few maturities higher natural gas the supplement, also this research area main existence early time oil gas pool - intermediate stage condensation gas pool - later period secondary shift clean oil deposit, the early oil gas pool destroy - the intermediate stage accumulation of gas - later period to shift concentrating to do gas pool, the preliminary accumulation of gas - later period again shifts concentrating to do the gas pool, the early oil gas pool again destroys - the intermediate stage accumulation of gas - later period to shift the concentrating wet gas pool four kinds to become the Tibet pattern...
